" B e it known that l, LEO GARLBnRenR, subject of the 'Emperor of Au'stria-'Hungary, re-

' siding at Vienna, Austriaeflung'ary, liaveine vented certain new and useful Im .rover me tsin lncub'ators', of. which the fol owing' is a .spetliiication -The present invention relatesy to an installation for incubating' simultaneously different species of eggsof poultry or eggs of one species, but of different sizes, in anyde sn'ed number., and consists substantially oi an-y number .of independent incubators with foster-mothers of Which eachfhas its seA arate heat regulator Qand' canbe. separately ad justed for" any'desired Worlyringv temperature.

These incubatorsand'` foster-mothers areinl' eluded 1n a common circuit of luidlwhich' circulates through all'the apparatus,v and by the Yaid of this fluid 'all the eggs in cloiursejofy manner the eggs are subjected to the action V `of 'heat'from above and from beloW,"andtoo much evaporation of th albuminous fluid is prevn d by automatically generated mois Isingle incubator. y l M reference characters' designate' corl I.

discharge pipes is provided with a turn-plug. as at 80. i V l rIhe reservoir 39 serves a dual purpose in '-that it receives all the liquid from the ,incucubators comprise storied frames 23 in which i eggs and tray 11.

are mounted boilers 24 suitably connected by double conduits 25 at b, b b2, c, c, and c2, d, d, and (I2. and e, c 4and `ethe said conduits being in turnconnected to inlet pipes 55` and outlet pipes 56. lyiinanipulating' the severalvalves or turn-plugs the liquid enters the several boilers 24 and thereby produces'a uiiiform'heat in each .'conpartment ,z or the boilers maybe switched in series and a variation in temperature in .each 'compartment produced. Below. the reservoir 1 in each instance are arranged, preferably, two pairs ot' .rollers g, g over which pass cords or ropes 9, which connect the cover 4 of the incubator with the solid counter-yveight'S and the Huid containing cliainbered counterweights 9 and 10.-' Interposed be'tyveen the suspending means is a stopping or arresting device 7- iiiounted on a c ord or strip 7a, the latter passing over rollers Sa and having counterweights S attached to each end.. The tray 11 comprises suitably spaced partitions 11a attached in' any Iconvenient manner to the trarne `and a flexible bttom 12iof pervious material supported by rollers 13 and 14'directly above the radiator pipes 15, each end of the'said bottom beingI connected to liquid receptacles 18 and 19, the latter eifecting 'the desired movement of the bottoni, and,'in consequence thereof, the turning ofthe eggs, as vvill be hereinafter eXplicitly referred to.

Then the predetermined head of pressure above the liquid outlets 29 has been attained by ineansof theimechanical power installa-l tion A and ythe turn-plug S0 of a'coininon discharge pipe 51 has been opened, the liquid aill the incubatore begins to circulate with -perfect uniformityT through the tube 6 as well as through. the moisture producing tank 16.

In lieu of turning the eggs in a manner as referred. to the tyvo rollers 13, 14. can be turned 'manually and since. this operation need not be vatt-ended to more oftenthan and thereby once in twenty-four hours, it' does not require anycoiisiderable amount of work.

Then it is `desired to air the eggs conipletely, the p'ipe'45 is opened so that the tanks 10 become filled, and the balance Weight-s 3 are thereby weighted so, heavily.
